Knock sensors are known problem!!!!!!!!!!!
Usually can fish them out with out removing manifold there are TWO
What codes exactly...
disconnect batt @ 30 min restart car may erase codes
The knock sensor is located on the top of the engine block almost hidden from view by the intake manifold. It is almost directly below the spot where your throttle cable connects. It will have a bolt running right through the middle of it and a single wire coming out of it.
the knock sensor itself can be faulty if there is a code showing for it.
CEL lights only come on if a sensor fails its diagnostic, it is nothing to do with the particular sensors readings, but telling you the sensor itself is bad.
The knock sensor is a little microphone attached directly to the cylinder block side wall.
did you buy it privately or a dealer w/ a warrantee? If you have a warantee, use it.If not start by changing the oil& see if that gives you any results.use the proper oil for Subaru,not a Quick Lube.
The light comes on when you climb a hill, accelerate quickly or do anything that advances the timing a lot and the knock sensor doesn't hear the knocks (pinging). The engine timing is not retarded, so you get a misfire.
The computer turns off the CEL if it sees the car start and run with no misfire of this nature 4 times in a row.
